[lttng-dev] lttng-tool cross configure for libxml2 error

[loody]

hi all
i use below configure command to cross-compile lttng-tool
./configure --disable-static --host=arm-v7a8v4r3-linux-gnueabi
CPPFLAGS=-I/media/sdb2/toolchain/arm/arm-v7a8v4r3-20131011/arm-v7a8v4r3-linux-gnueabi/sys-root/include
--prefix=/media/sdb2/toolchain/arm/arm-v7a8v4r3-20131011/arm-v7a8v4r3-linux-gnueabi/sys-root/

But get below message:
checking for libxml - version >= 2.7.6... no
*** The xml2-config script installed by LIBXML could not be found
*** If libxml was installed in PREFIX, make sure PREFIX/bin is in
*** your path, or set the XML2_CONFIG environment variable to the
*** full path to xml2-config.
configure: error: No supported version of libxml2 found.

I use below git commit version to cross-compile:
   commit 83b7c3bf7a5c28883396af5dadd6ee469f20aa59
   Author: David Goulet <dgoulet at efficios.com>
   Date:   Wed Mar 26 11:31:36 2014 -0400
      Fix: update test to use correct lttng load option
      Signed-off-by: David Goulet <dgoulet at efficios.com>

My questions are
1. is that necessary for lttng run on arm platform with xml support?
2. Is it possible to disable xml support with configure command?
3. I use "--disable-xmltest" option, but configure still said it need libxmll

Thanks for your help in advance,

I found what I am wrong ^^
after install libxml2-dev lib in my host, configure is ok.
